In the article “Proteomic Analysis in Aortic Media of Patients With Marfan Syndrome Reveals Increased Activity of Calpain 2 in Aortic Aneurysms” by Pilop et al, which appeared in the September 15, 2009 issue of the journal (Circulation. 2009;120;983–991), the Sources of Funding on page 990 was incorrect and should read:
“This work was supported by the Swiss National Foundation for Scientific Research grants 3100A0-102153 and 320000-122135/1 to Dr Frey and grant 3100A0-120504 to Dr Matyas. Drs J.H. Gorman and R.C. Gorman were supported by individual Established Investigator Awards from the American Heart Association (Dallas, Tex).”
